This Echidna figure from the Aqua Float Girls line is designed to evoke a tranquil pool scene while staying true to her Witch of Greed persona. She is posed with graceful balance, one hand lifted as if measuring knowledge, and a calm, knowing expression that hints at her centuries of study. The sculpt captures her refined features, flowing lavender hair, and a sleek, water-inspired outfit with translucent accents. The base recreates a glossy pond surface with ripples and bubbles, while the color palette uses deep purples, teals, and soft whites to convey elegance and mystery. The overall presentation blends character charm with a playful summery vibe.

Echidna, the Witch of Greed in Re:Zero kara Hajimeru Isekai Seikatsu, is introduced as a scholar of forbidden knowledge and a patient, incisive observer of humans and spirits. In the story, she seeks to test Subaru's resolve and to learn more about the world's cycles and limits. Her interactions reveal a paradox: an insatiable hunger for learning paired with a compassionate, protective side toward those she becomes attached to. The figure captures that complexity by pairing her elegant, contemplative gaze with a pose that suggests both wisdom and a hint of mischief. This description reflects her allure as a character who values intellect as much as power.
